GEM-SETTING.

SPECIFICATION forming part of Letters Patent No. 396,092, dated January 15, 1889.

Application filed May 26, 1888- $erial No. 275,233. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID KUTNER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Gem-Settings, of which the following is a specification.

My invention relates to an improved setting for gems, and is applicable to finger-rings, brooches, lockets, sleeve-buttons, and other jewelry; and it consists in an improved gem box or setting provided with suitable setscrews for holding the gem in position.

My invention is shown in the accompanying drawings, in which like letters of reference indicate corresponding parts of my invention.

Figure 1 is a top view of a finger-ring, showing myinvention applied to the same and holding the gem in position. Figs. 2, 3, and 5 are side views of the same. Figs. 4; and 8 are side views of the gem provided with suitable openings to receive the end of the setscrew, of which my invention in part consists. Figs. 6 and '7 are enlarged views of the setscrew, of which my invention in part consists.

A represents the gem-box of a finger-ring to which my invention is applied.

a is the set-screw,which plays in the threaded openings on opposite sides of the gem-box. This set-screw terminates in the flattened end a.

b is the opening in side or end of the gem provided with the slotat its lower edge (shown in Fig. 8) to permit the gem to drop into place without removing the set-screw.

My invention is used as follows: The setscrews are screwed in position and turned so that the thin or flattened edges of the screws respectively stand upright. The gem is then dropped into the box so that the slotted opening falls over the thin end of the screw, as shown in Fig. 8. The screws are respectively given a half-turn, so that the flattened end stands across the slotted opening, as shown in Fig. 4. The gem is now secured and cannot be removed except by returning the set-screw, so that it will pass through the slot. The same arrangement and construction are adaptable to any species of jewelry to readily admit the changing of the gem either for the convenience of the tradesman or the gratification of the taste of the wearer.

Having fully described my invention, what I claim, and desire to secure, is

The improved gem-box A, provided with the set-screws a a, terminating in the flattened portions a a, in combination with the gem B, provided with the slotted opening b, substantially as and for the purpose set forth.

Signed at New York city, in the county of New York and State of New York, this 17th day of May, A. D. 1888.

DAVID KUTNER.
